Answer:

a vaccine of the old virus may not work for the new one cuz all the virus are not the same

A vaccine is made of which the virus is totally vanished and even if the same virus enters ur body. There will be no effect on u cuz the first time you got they insert the vaccine into you and the antibiotic will be present in your body to defend it and kill it where as it is not the same case for cold
